Actor Shin Ha Kyun commented, "I chose this particular project because it had a realistic story, mixed in with a bit of fun. I believe it's a story many generations would be able to relate to."
EXO's D.O. also mentioned, "When I read the script, I found it so entertaining. This will be my first time taking on a dark comedy genre and I always wanted to act out a figure like my character. I even got a tattoo just for this role," describing how immersed he was in his work.
Meanwhile, 'Room 7' is set to hit theaters in November.
